DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1 to Figure 3 , an adjustable formwork for a curved assembled pavement, comprising a transverse straight formwork 1, a curved side formwork 2, and a buckling assembly 3; two of the transverse straight forms 1 are arranged opposite to each other, two of the curved side forms 2 are arranged opposite to each other, and two ends of the two transverse straight forms 1 and the two curved side forms 2 are connected in sequence through the buckling assembly 3, together forming a fan-shaped ring structure;

[0028] The buckling assembly 3 includes a buckling plate 31, a buckling plate body 32, a buckling connector 33, and a buckling slide bar 34. The buckling plate body 32 is horizontally arranged, one end of the buckling plate body 32 is connected to the buckling plate 31 arranged vertically, the other end of the buckling plate body 32 is connected to the buckling connector 33, and the buckling slide bar 34 is connected to the lower surface of the middle part of the buckling plate body 32;

[0029] The upper surface of the transverse straight mold 1 is provided with a slide groove 5 corresponding to the buckling slide rod 34, and the buckling plate 31 is buckled on the outer surface of the transverse straight mold 1; the upper side surfaces at both ends of the curved side mold 2 are provided with cavities for inserting the buckling connector 33.

[0030] In the above technical scheme, two relatively arranged transverse straight molds 1 and two relatively arranged curved side molds 2 constitute the main structure of the adjustable mold, and the overall mold is a fan-shaped structure; it can be understood that the two transverse straight molds 1 are straight and have the same specifications (length, width and height); the two curved side molds 2 are slightly curved, one is longer and the other is shorter; the arc surface of the curved side mold 2 is approximately perpendicular to the straight surface. With such an arrangement, when it is closely connected with the transverse straight mold 1, it can fit more closely without leaving obvious gaps, which is beneficial to the fixed connection between the curved side mold 2 and the buckling assembly 3, thereby improving the production quality of the prefabricated board.

[0031] The outer surfaces of both ends of the transverse straight mold 1 are respectively buckled with buckling plates 31, and the buckling plate body 32 is placed on the upper surface of the transverse straight mold 1, and the buckling slide bar 34 on the lower surface of the middle part of the buckling plate body 32 can slide along the slide groove 5 opened on the upper surface of the transverse straight mold 1 to adjust the width of the fan ring template; after the buckling plate body 32 slides to the required width of the curved road surface, a limiting steel bar can be placed in the slide groove 5 for limiting. Of course, the edge of the slide groove 5 can also be marked with scales to facilitate timely grasping of the width of the template.

[0032] The cavity formed on the upper side surface of the curved side mold 2 is used to accommodate the insertion of the buckle connector 33. This arrangement can stabilize the installation of the buckle assembly 3, so that the horizontal straight mold 1 and the curved side mold 2 form a relatively stable whole. It can be understood that a certain thickness is left above the cavity formed on the side of the curved side mold 2 to cover the buckle connector 33.

[0033] As a more preferred technical solution of this embodiment, a first threaded hole 331 is formed on the pressing connector 33, and a second threaded hole 4 corresponding to the first threaded hole 331 is formed on the upper surface of the curved side mold 2. In this way, the curved side mold 2 and the pressing connector 33 are fastened by inserting bolts, thereby achieving the overall fastening of the transverse straight mold 1 and the curved side mold 2.

[0034] As a more preferred technical solution of this embodiment, the inner side surface of the horizontal straight mold 1 is riveted with a first connecting tube 6, and the first connecting tube 6 is provided with a first opening for the steel bar to pass through. The number of the first connecting tubes 6 is 2, and they are respectively arranged near the two ends of the horizontal straight mold 1. The inner side surface of the curved side mold 2 is provided with a second connecting tube 7, and the second connecting tube 7 is integrally formed with the curved side mold 2; the second connecting tube 7 is provided with a second opening for the steel bar to pass through. The number of the second connecting tubes 7 is 2, and they are respectively arranged near the two ends of the curved side mold 2. The first connecting tube 6 and the second connecting tube 7 can both be cylindrical hollow coppers made of steel; the first connecting tube 6 needs to change its installation position according to the different widths of the template, so it is installed and set on the inner side of the horizontal straight mold 1 by riveting, which is convenient for disassembly; and the second connecting tube 7 on the curved side mold 2 does not need to change its relative position with the curved side mold 2, so the second connecting tube 7 and the curved side mold 2 can be integrally formed. Openings are provided on the first connecting tube 6 and the second connecting tube 7, through which the connecting steel bars are inserted, and the installed four main bars can also be used as lifting steel bars.

[0035] As a more preferred technical solution of this embodiment, the buckling plate 31, the buckling plate body 32, the buckling connector 33 and the buckling slide rod 34 are integrally formed.

[0036] As a more preferred technical solution of this embodiment, the material of the horizontal straight mold 1 and the curved side mold 2 are both aluminum alloy, which has high strength, light weight and corrosion resistance. The thickness of the horizontal straight mold 1 and the curved side mold 2 are both 100mm, the maximum width of the mold can be 4m, and the maximum sliding distance can be set to 1m.

[0037] The above embodiment is further described with the following application examples:

[0038] In this specific application example, in the construction of a temporary access road project with a circular curve radius of 150m, the length of the circular curve is 40m and the road surface width is 3.5m. The design and calculation result shows that the length of the outer curve side mold of the curved road surface template is 4m, the radius of curvature is 150m, the length of the inner curve side mold is 3.85m, and the radius of curvature is 150m.

[0039] After the template is made in the factory, the positions of the various plates are arranged at the prefabrication site. The two horizontal straight molds 1 are on both sides of the arc-shaped plate 2, and then the four buckling components 3 are respectively installed on both sides of the horizontal straight mold 1. The buckling component 3 is clamped on the horizontal straight mold 1 through the buckling plate 31 and the buckling slide rod 34. There is a buckling connector 33 close to the inner side of the horizontal straight mold 1, and the whole is firmly placed on the horizontal straight mold 1; after the buckling component 3 is installed, slide the buckling component 3 in the slide groove to the corresponding scale until the plate width is The distance between the curved side mold and the horizontal straight mold 1 is 3.5m, and a limit steel bar is placed to limit the position. The steel bar is filled in the slide groove 5, so that the buckling slide bar 34 cannot move, so as to achieve the purpose of limiting the position. Then two main bars are placed in the first connecting tube 6 and the second connecting tube 7 respectively, which are convenient for connection and hoisting. Then the buckling connector 33 is placed in the cavity of the curved side mold 2, and the curved side mold 2 is tightly fitted with the horizontal straight mold 1. Then the connecting bolts are installed above the curved side mold 2 and the buckling connector 33 is fastened to form an integral and stable fan ring template. Finally, the installed template can be used to make the road panel.

[0040] The present invention illustrates the technical concept of the present invention through the above embodiments, but the present invention is not limited to the above embodiments, that is, it does not mean that the present invention must rely on the above embodiments to be implemented. Those skilled in the art should understand that any improvement of the present invention falls within the protection scope and disclosure scope of the present invention.
